Disposable medical needle tip guard

Abstract

The invention discloses a needle tip protection device of a disposable medical needle. The needle tip protection device comprises a shell, wherein an opening for a needle tube of the medical needle to penetrate through is formed in the first end of the shell; a pressing plug is arranged at the top part of the shell; the end part of the pressing plug is connected with a cutter; the bottom part of the shell is provided with a supporting platform; the supporting platform is positioned under the cutter; a gap which is used for a needle head of the medical needle to penetrate through is reserved between the cutter and the supporting platform. According to the needle tip protection device disclosed by the invention, a needle tip can be bent so as to damage the needle head; meanwhile, due to the protection of the tail part of the shell and a clamp, the needle tip cannot expose outside, and people can be prevented from being hurt.

Description

technical field [0001] The invention relates to a disposable medical needle tip protection device, which belongs to the technical field of medical instruments. Background technique [0002] Medical needles, such as hypodermic needles, biopsy needles, intravenous introducers, trocars, guide wires, thoracentesis needles, etc., after use, these will become dangerous goods after they are contaminated with drugs or pathogens on patients, and due to accidental use by these There are too many cases to be punctured by instruments with needles. In order to avoid the health risk of being punctured by such contaminated thorns or infected thereby, there are some protective devices in the prior art, but some of the existing protective devices protect If it is not in place, it is often possible to suffer secondary injuries.

[0002] Medical needles, such as hypodermic needles, biopsy needles, intravenous introducers, trocars, guide wires, thoracentesis needles, etc., after use, these will become dangerous goods after they are contaminated with drugs or pathogens on patients, and due to accidental use by these There are too many cases to be punctured by instruments with needles. In order to avoid the health risk of being punctured by such contaminated thorns or infected thereby, there are some protective devices in the prior art, but some of the existing protective devices protect If it is not in place, it is often possible to suffer secondary injuries

[0003] Furthermore, the existing various medical needles are disposable, and after use, they are simply put on the needle cap and discarded immediately. Because the needle cap is not firm, it will also cause harm to the staff who handle these medical wastes, and even some Lawbreakers recycle these discarded medical needles, which poses a greater safety hazard. The existing technology has not yet found a more thorough protection device for this situation, which will completely damage the used needles, which can not only avoid stab wounds but also Prevent recycling by those who care
